support with writing little php / javascript script

Happy new year!

I need help with writing little conditional php / javascript script

currently i have this script:

<div class="myDiv">
<div id='databalue2'>
<label for="name" class="label-bb">



<?php if (!empty($image1)) {
echo ' <span><img style="position: relative; width: 220px; height:200px; max-height: 200px; max-width: 220px;"src="' . $image1 .'"> </span><span id="nodisable"></span>';
}else{ ?>

<center><img style="position: relative; width: 220px; height:200px; max-height: 200px; max-width: 220px;" src="baro_files/images/loading-qr.gif"</center>
<?php } ?>

</label>
</div>
</div>
